However, over the last several years we’ve seen a barrage of successful missions by every country’s space programs and also by private companies. We’ve been exploring distant objects like Pluto, nearer objects like comets, and in-between enormous objects like Jupiter. Oh, and we’ve been driving on Mars every day for years. To top it off we’re now routinely sending objects into orbit around the earth and landing back on the ground. It is a very, very exciting time.

It isn’t too late. We can catch up from the last few decades in a hurry and I’m really happy that two brave and obviously wealthy human beings are willing to push us all forward. All the best to them. Have a great trip.
